Abstract

FIELD: construction. ^ SUBSTANCE: method includes making gabion mats from mesh grid, which is folded twice, with arrangement of hollow cylinders between the layers. In areas of cylinders adjacency the layers of grid are tightly sewn to each other with a binding wire, breaking the produced mat into separate cylindrical sections. The hollow cylinders are tightly filled with stones. Afterwards the hollow cylinders are withdrawn from the mat, and ends are plugged with plugs. ^ EFFECT: increased efficiency in making cylindrical gabion mats, efficiency and reliability of slopes protection, shores, river and canal beds against washing and higher durability of the facility service life. ^ 4 cl, 3 dwg

Description

The invention relates to environmental and hydraulic engineering construction and can be used to protect slopes from erosion, as shore protection structures in eroded riverbeds, canals and other structures during emergency recovery work, as well as during major construction in difficult conditions.

A known method of erecting a gabion mount [1], including laying along the banks of the channel on the base of a stone-filled gabion prismatic shape. The disadvantages of this technical solution are:

- such a technical solution is inefficient to use when conducting emergency recovery work;

- the rigidity of the gabion structure is insufficient;

- economically, it is not a favorable technical solution.

The closest technical solution is the method of erecting a gabion mount in flowing water [2], including laying along the banks of the channel of the gabion mattresses filled with stone.

The disadvantages of this technical solution are:

- such a technical solution is inefficient to use when securing slopes in large areas;

- with this method of filling with stones, it is not possible to perform cylindrical gabions with exactly the same dimensions, which affects the quality and strength of the gabion mattresses;

- this technology is not allowed to produce thin structures, thick structures are not economically a favorable technical solution.

The purpose of the invention is to increase productivity in the manufacture of cylindrical gabion mattresses, the effectiveness and reliability of the protection of the slopes and banks of riverbeds and canals from erosion and durability.

This goal is achieved by the fact that the unwound roll of woven mesh is doubled so that the total length is approximately 1.0 ÷ 2.0 m, and the width is 0.5 ÷ 1.0 m. Hollow plastic cylinders are placed between the layers, the diameter of which depends on the purpose gabion mattresses and varies between 0.05–0.5 m. So, thin gabion mattresses are needed to strengthen the slopes from erosion processes, and powerful ones are needed to strengthen the lower pools of water discharge and spillway hydraulic structures. At the joining points of the hollow plastic cylinders, the mesh layers are stitched together with a strapping wire 1.5–2 mm thick. Further, the hollow plastic cylinders are densely filled with stones. After that, the hollow plastic cylinders are removed from the mattress, and the ends are plugged with plugs that are securely attached to the gabion mattress.

Figure 1 shows a halved roll of woven mesh, general view; figure 2 - manufacturing technology of gabion mattress, axonometry; figure 3 - manufactured gabion mattress, axonometry.

The expanded roll of woven mesh 1 is doubled and hollow plastic cylinders 2 are placed between the layers. The hollow plastic cylinders 2 are densely filled with stones 3. Before filling with stones 3, the woven mesh 1 is sewn with strapping wire 4 at the junctions of the hollow cylinders 4. Then the hollow plastic cylinders 2 are removed from the mattress, and the ends are clogged with caps 5.

The method of construction of a gabion mattress is as follows. The expanded roll of woven mesh 1 is doubled so that the total length is approximately 1.0 ÷ 2.0 m and the width is 0.5 ÷ 1.0 m. Hollow plastic cylinders 2 are placed between the layers, the diameter of which depends on the purpose of the gabion mattresses and varies between 0.05 ÷ 0.5 m. So, to strengthen the slopes from erosion processes, thin gabion mattresses are needed, and powerful ones are needed to strengthen the lower downstream water discharge and spillway structures. At the junctions of the hollow plastic cylinders 2, the layers of the woven mesh 1 are sewn together with a strapping wire 4. Next, the hollow plastic cylinders 2 are densely filled with stones 3. The diameter of the stone 3 is larger than the mesh size of the woven mesh 2 so that the stone 3 does not fall out of gabions. After that, the hollow plastic cylinders 2 are removed from the mattress, and the ends are plugged with plugs 5, which are securely attached to the gabion mattress.

The proposed method for the construction of a gabion mattress can significantly increase labor productivity in manufacturing. Gabion mattresses made using this technology have a highly aesthetic appearance due to the fact that all cylinders have exactly the same dimensions. The quality of the gabion mattress, and therefore the bearing capacity, is much higher than that of the analogue.

Gabion mattresses are environmentally friendly technical solutions, and the durability of these structures is 1.5-2 times more than analogues.
